I have a really old Novell server sitting here which has a corrupt Directory Service database. It's kind of a long story... the server hard drive failed, sent it to data recovery, got a solid sector for sector image, transferred that back to a new drive, and booted up the server. Everything works fine except that Novell dies during startup complaining about the directory services. When I ran the DSREPAIR it found 35 errors and said a lot of scary things like "filling with 0" and then after that, the directory services would load but the server would lock up anytime you tried to do anything with the directory services and users could not authenticate. I can reimage the drive and get it back to it's original state. But I'm hoping there is a way of maybe rebuilding the directory service instead of repairing which doesn't seem to work.
